Confusion about mobile packages has led to nine out of ten people saying they felt short-changed by their phone contracts, according to new service provider Noodle.

It found that three-quarters of people did not make sufficient calls to justify their monthly contract, or conversely, they regularly go over their monthly minute allowance.

However, the figures also showed that pay-as-you-go mobile phones are the most popular in the UK, with 55% of mobile users opting for this type of service, Ananova reported.
